Sunday, March 27th, 2011

Rosser Reeves Star Ruby gets its name from its one time owner Rosser Reeves, the advertising magnate and pioneer of television advertising, whose techniques were very popular in the 50s and 60s, and gave a successful boost to the election campaign of Dwight D. Eisenhower in 1952, which led to his election as the 34th President of the United States of America. Reeves purchased the Star Ruby in the mid 1950s, and since then the stone was his constant companion, and carried it around wherever he went, in the belief that it brings good luck. Subsequently in the year 1965, Mr. & Mrs. Rosser Reeves donated the renowned gemstone to the National Museum of Natural History, of the Smithsonian Institution, where it has now become one of the most prized possessions of the Institution.

The Rosser Reeves Star Ruby is a 138.7-carat red star ruby of Sri Lankan origin, and like all other star rubies have been cut as a cabochon to bring out the well defined, six-legged, centrally placed star. The outstanding character of this unique gemstone is that it combines the rare features of excellent color, translucency and well defined star, making it perhaps the largest and finest star ruby in the world. In this respect the Rosser Reeves surpasses the next biggest and equally famous red star ruby the 100.32-carat DeLong Star Ruby, which is displayed at the American Museum of Natural History in New York. The longest length-wise, and breadth-wise diameters and the thickness of the stone are 31.5mm, 26.5mm and 19.08mm respectively.
